Not all Coroner's cases are autopsied. Certain cases are not autopsied where no "foul play" is suspected and evidence of a natural death is present. In other cases where there is the possibility of legal proceedings which may arise as a result of a homicide, accident, suicide, etc., an autopsy will be performed. In these cases both positive and negative information is found which substantiates the ruling and cause of death as signed by the Coroner. If an autopsy was ordered during the investigation process the final report may take 12-16 weeks to complete. Toxicology studies, if ordered, may take 8-10 weeks to complete.
